As an important composition of terahertz (THz) technology, THz pulsed focal-plane imaging has been paid widely attention since it was invented. Until now, researchers have introduced all kinds of methods to enhance the performance of this imaging technique. Simultaneously, this imaging technique has been tried to apply into various industrial and fundamental research fields. In this paper, recent technique improvements and application researches for THz pulsed focal-plane imaging are reviewed, including the spatial resolution enhancement, signal-to-noise ratio improvement, information acquiring ability as well as applications of this imaging technique in spectroscopic identification inspections, function demonstrations of meta-surface devices, measurements of THz special beams, observations of THz surface electromagnetic waves, and so on. The aim of this paper is to push the technique innovation and application exploration of THz pulsed focal-plane imaging.
